CLINICAL THERMOMETER.

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed May 25,' 1912. Serial No. 699,773.l

To all whom t may concern Be it known that I, WILLIAM MARION Bevis, acitizen of the United States, residing at Lakeland, in the county ofPolk and State of Florida, have invented certain new and usefulImprovementsin Clinical Thermometers, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in clinicalthermometers and more particularly to an antiseptic case therefor, andmy object is to provide a case of this character adapted to containantiseptic fluid which will removeall germs or the like from thethermo-meter, as the same is placedy therein.

A further'object of the invention resides in providing a case formed insections, the one section of which is provided with means to prevent theantiseptic fluid from flowing therefrom.

A still further object of the invention resides in providing va devicewhichA is extremely simple and durable in construction, inexpensive tomanufacture and one which will be very efhcient and useful in operation.With these and other objects in view, the

yinvention consists in the novel features of construction, combinationand arrangement of parts as will be hereinafter referred to and moreparticularly pointed out in the specification and claim. y

In the accompanying drawing forming a part of this application, Figure lis a side elevation of the device. IF ig. 2 is a vertical sectiontherethrough; and Fig. 3 is a horizontal section4 through the same, asseen on line 3-3, Fig. 2.

In describing my invention, I shall refer to t' e drawing in whichsimilar reference characters designate corresponding parts throughoutthe several views and in Which- 1 indicates a cylindrical barrel orcasing formed of the sections 2 and 3 which are threaded into engagementwith one another as shown at 4. The bore of the section 2'of said barrelor casing isquite small and the bore of the section 3 at that portionthereof connecting with the section 2, is of a similar diameter, but.this restricted bore ofthe latter section 3 communicates with an e11-larged bore or cavity 5 which extends for the greater portion of thelength of said section 3, the walls of the bore o r cavityv 5 taperingtoward the restricted bore, as shown atI 6. The upper or outer end `ofthe section 3 is provided with a contracted opening or neck portion 6which is threaded, and formed integral with this neck portion of thesection is a tube or the like 7 which extends longitudinally intothesection 3 and terminates at a point a short distance above the point ofcommunication between the enlarged bore portion thereof.

A cap or head member 8 is adapted to be applied to the upper or outerend of the sec- Ition 3, saidcap or head being provided with a threadedshank or the like 9 to be engaged with the threaded neck portion 6 andsaid cap member is provided with a central channel 10 to snugly receivetherein one end of a clinical thermometer :'11. Thus when the cap member8 with t 'e thermometer ll applied thereto is properly applied to thesection 3, said thermometer will be disposed through the tube 7 and intothe restricted lbores of the sections 2 and 3 and as the restricted boreofthe section 2 is adapted to contain an antiseptic fluid, it will beunderstood that germs 'or the like on the thermometer will bereadilyremoved. That portion of the neck 6 of the section 3 connecting the tube7 thereto is slightly tapered as shown at 12 and the end ofthe shank 9is similarly tapered to fit snugly thereagainst when said cap isproperly applied to the device and thus it will be practicallyimpossible for the fluid within the device to leak therefrom, shouldsaid fluid find a passage-way through the tube 7. 1

o andthe restricted bore portionl In practice, the section 2 of thebarrel or casing'is filled with an antiseptic fluid to a poi'ntimmediately adjacent the neck or threaded portion thereof, whereupon thesection 43 is properly applied thereto. The cap 8 with the thermometeryl1 pro mounted therein is then applied to the sec# tion 3 and as thethermometer 11 is inserted in the section 2, the fluid therein will, ofcourse, rise to the level o-f the plane at which the tapered portion 6of the -bore 5 communicates with the restricted bore portionof saidsection 3. Thus it will be seen that the perly 4 thermometer 11 willhave the greater portion `thereof inserted in the antiseptic fluid whenpro-perly disposed in the casing. When the cap 8 with the` thermometer11 is removed from the casing for practical purposes, the operator mayallow the casing to rest horizontally on a flat surface without dangerof the iuid iiowing from the same for, as the device is placed on thesurface, said fluid will flow into the cavity or enlarged bore 5surrounding the tube 7.v As the space from the wall of the tube 7 to thewall of the section 3 proper, is considerably greater than the diameterof the restricted bore of the section 2, the fluid therein, when thedevice is in a-horizontal position on a fiat surface,

will never reach a point whereby it may iow through the tube 7 and thusthe device may be completely inverted and the fluid therein willentirely surround the tube 7 but will not ow Itherefrom.

It is `perfectly natural for one using a clinical thermometer to placethe case therefor flatly upon a table or the like, but considerableinconvenience has heretofore been experienced in the placing of suchcases upon a table, since the same have not been provided with suchmeans as to prevent the iiuid from iiowing therefrom. With a device suchas I yhave provided however, no

tion may be resorted'to without departing from the spirit or sacrificingany of the principles of the invention.

Having thus described this invention, what I claim is A case forclinical thermometers comprising a tubular casing closed at one endthereof and provided with a restricted bore extending the greaterportion of the length of the same, said restricted bore being adapted tocontain a liquid and terminating in an enlarged bore at the upper end ofthe casing, said enlarged bore having the Walls'at the lower endsthereof tapered toward said .restricted bore, the open end of saidcasing being threaded, a tubular extension disposed within said enlargedbore to a point above the junction of the enlarged and restricted hores,the upper end of said tubular extension being fiared outwardly andformed integral with the walls of the open end of said casing, and a caphaving a shank thereon adapted to be disposed in the open end of saidcasing, said shank being threaded for a portion of its length to engagethe threads of the casing and also tapered for a portion of its lengthto contact with the Haring upper end of said tubular extension.

In testimony whereof I hereunto aix my signature in the presence of twowitnesses.

WILLIAM MARION BEVIS.
